trunk-group

Last Updated : Nov 06, 2012 |

Used within the sls context to enter a second-level subcontext for administering trunks for SLS. After issuing this command, the prompt changes to sls-trunk-group-<tgnum>. Type exit to leave the trunk-group context, and return to the sls context.

Syntax

trunk-group tgnum [group-type]

Parameters

Parameter

Description

Possible Values

Default Value

tgnum

The required trunk group number

1-2000

group-type

The trunk group type. This argument is required to enter the trunk-group context.

loop-start (analog)

did (analog)

ground-start (analog)

bri (ISDN basic rate)

t1isdn (ISDN primary rate on 1.544 Mbps facility)

e1isdn (ISDN primary rate on 2.048 Mbps facility)

t1inband (non-ISDN rate on 1.544 Mbps facility)

e1inband (non-ISDN rate on 2.048 Mbps facility)

You can create a trunk group that does not have any assigned members. Once a valid port is assigned as a trunk group member, this trunk group becomes active and may be employed by SLS call processing for incoming/outgoing trunk operation. The slot-configuration table will be used together with the port capacity for the given module to determine the validity of a port assignment at administration time.

As a corollary to this, there may not be more active trunk groups than there are physical trunk members within a given gateway. Secondly, a combo-port may only be used for one active assignment. For example, the analog station/DID trunk ports may be either allocated to serve as an analog station or as an analog DID trunk, but not BOTH.
